New data show that the 13 states that raised the minimum wage this year are adding jobs at a faster pace than those that did not.

State-by-state hiring data released Friday by the Labor Department reveal that in the 13 states that boosted minimum wages at the beginning of this year, the number of jobs grew an average of 0.85 percent from January to June. The average in the other 37 states was 0.61 percent, the Associated Press reports.

The findings could undermine the argument that raising the minimum wage hurts job growth, a view held by major conservative lobbies. The Congressional Budget Office reported earlier this year that a minimum wage of $10.10 could bring 900,000 people out of of poverty, but would cost 500,000 jobs nationwide.

“It raises serious questions about the claims that a raise in the minimum wage is a jobs disaster,” said John Schmitt, a senior economist at the liberal Center for Economic and Policy Research. The job data “isn’t definitive,” he added, but is “probably a reasonable first cut at what’s going on.”

President Barack Obama has supported raising the minimum wage, saying that it will help the economy and businesses.

Some economists said that data was inconclusive and that it’s too early to say whether minimum wage hikes hurt job growth. The rate of job growth was the highest in North Dakota, where the local oil and gas boom has spurred the economy but there has been no minimum wage increase. “It’s too early to tell,” said Stan Veuger, a scholar at the American Enterprise Institute. “These states are very different along all kinds of dimensions.”
